Re: Premier only on 36meg speed despite having much more available
Originally my Express was getting 8-10mbs but I changed the channel on the router and got it up to 20-22mps. That didn't change anything I could see because typical HD streaming needs about 5mbps. (Though if you do 4K, you might want more like 25mbps.) Generally, I think it's pretty well understood that Rokus don't (and weren't designed to) set network benchmark records. Their networking is just meant to be fast enough for their main tasks of streaming TV.
That said you could try changing channels. No guarantees of course.
